摘要:

为应对侧信道能量信息泄漏检测中的多重t检验问题，提出了一种控制多重t检验过程的错误识别率并提升检验效力的泄漏检测方案。在对多重假设检验问题进行分析的基础上引入错误识别率和检验效力作为多重t检验过程中的控制参量。介绍了已有控制多重假设检验问题的方案，结合泄漏检测过程，通过提升检验阈值和调整检验水平的方法对已有控制方案进行了改进，并进行了实验验证。验证结果表明该方案能在提升能量信息泄漏检测能力的同时将检验差错控制在一定范围内。

Abstract:

To cope with the multiple t-test issue in the leakage detection of side-channel power information, a leakage detection scheme is proposed to control the false discovery rate of the multiple t-test process and improve the test effectiveness. Based on the analysis of multiple-hypothesis testing issue, the false discovery rate and test effectiveness are introduced as control parameters in the multiple t-test process. Existing schemes for controlling multiple-hypothesis testing issue are introduced. Combined with the leakage detection process, the method of raising threshold and adjusting the test level is proposed to improve the existing control scheme, which is verified by experiments. The verification results show that this scheme can improve the detection capability of power information leakage and control the test errors within a certain range.
